|

|
||||
==== Count Request
|
||||
|
||||
The +{request}+ is used to execute a query and get the number of matches for the query. The query to use in +{request}+ can be
|
||||
set in similar way as query in `SearchRequest` using `SearchSourceBuilder`.
|
||||
|
||||
In its most basic form, we can add a query to the request:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-request-basic]
|
||||
--------------------------------------------------
|
||||
|
||||
<1> Creates the +{request}+. Without arguments this runs against all indices.
|
||||
<2> Most search parameters are added to the `SearchSourceBuilder`.
|
||||
<3> Add a `match_all` query to the `SearchSourceBuilder`.
|
||||
<4> Add the `SearchSourceBuilder` to the +{request}+.
|
||||
|
||||
[[java-rest-high-count-request-optional]]
|
||||
===== Count Request optional arguments
|
||||
|
||||
Let's first look at some of the optional arguments of a +{request}+:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-request-indices-types]
|
||||
--------------------------------------------------
|
||||
<1> Restricts the request to an index
|
||||
<2> Limits the request to a type
|
||||
|
||||
There are a couple of other interesting optional parameters:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-request-routing]
|
||||
--------------------------------------------------
|
||||
<1> Set a routing parameter
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-request-indicesOptions]
|
||||
--------------------------------------------------
|
||||
<1> Setting `IndicesOptions` controls how unavailable indices are resolved and how wildcard expressions are expanded
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-request-preference]
|
||||
--------------------------------------------------
|
||||
<1> Use the preference parameter e.g. to execute the search to prefer local shards. The default is to randomize across shards.
|
||||
|
||||
===== Using the SearchSourceBuilder in CountRequest
|
||||
|
||||
Both in search and count API calls, most options controlling the search behavior can be set on the `SearchSourceBuilder`,
|
||||
which contains more or less the equivalent of the options in the search request body of the Rest API.
|
||||
|
||||
Here are a few examples of some common options:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-source-basics]
|
||||
--------------------------------------------------
|
||||
<1> Create a `SearchSourceBuilder` with default options.
|
||||
<2> Set the query. Can be any type of `QueryBuilder`
|
||||
|
||||
After this, the `SearchSourceBuilder` only needs to be added to the
|
||||
+{request}+:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-source-setter]
|
||||
--------------------------------------------------
|
||||
|
||||
Note subtle difference when using `SearchSourceBuilder` in `SearchRequest` and using `SearchSourceBuilder` in +{request}+ - using
|
||||
`SearchSourceBuilder` in `SearchRequest` one can use `SearchSourceBuilder.size()` and `SearchSourceBuilder.from()` methods to set the
|
||||
number of search hits to return, and the starting index. In +{request}+ we're interested in total number of matches and these methods
|
||||
have no meaning.
|
||||
|
||||
The <<java-rest-high-query-builders, Building Queries>> page gives a list of all available search queries with
|
||||
their corresponding `QueryBuilder` objects and `QueryBuilders` helper methods.
|
||||
|
||||
include::../execution.asciidoc[]
|
||||
|
||||
[id="{upid}-{api}-response"]
|
||||
==== CountResponse
|
||||
|
||||
The +{response}+ that is returned by executing the count API call provides total count of hits and details about the count execution
|
||||
itself, like the HTTP status code, or whether the request terminated early:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-response-1]
|
||||
--------------------------------------------------
|
||||
|
||||
The response also provides information about the execution on the
|
||||
shard level by offering statistics about the total number of shards that were
|
||||
affected by the underlying search, and the successful vs. unsuccessful shards. Possible
|
||||
failures can also be handled by iterating over an array off
|
||||
`ShardSearchFailures` like in the following example:
|
||||
|
||||
["source","java",subs="attributes,callouts,macros"]
|
||||
--------------------------------------------------
|
||||
include-tagged::{doc-tests-file}[{api}-response-2]
|
||||
--------------------------------------------------
